Atomic structure and isotopes quizzes

 Revising Atomic structure and Isotopes with quizzes

(Simple Atomic Structure and Isotopes quizzes for students going in for the GCE, GCSE, and necta)

In this section, our point of focus will be Atomic structure and Isotopes. Here, you'll get to study the structure of the atom, isotopy, etc Below are ready-made quizzes to assist you in your revision. Before that, let's look at the definition of the various key terms required for this quiz

 An atom is the smallest unit of matter that forms a chemical element. The size of an atom is too small (about 100pm) and it is made up of neutral ions or atoms. A standard atom has a nucleus (made up protons and neutrons), and at least one or more electrons. A normal atom is electrically neutral, due to the equality in number between the positive and the negative charges. When there is a difference in charges, it is known as an ion.

Definition of some terms 

The following terms should be understood in order to enjoy this quiz.

Nucleus: This is a collection of neutral and positive subatomic particles.

Shell: An orbit followed round the nucleus by electrons.

Nucleons: The subatomic particles found in the nucleus (protons and neutrons)

Neutron: Subatomic particle (nucleon) with no net charge at all.

Electron: This is the subatomic particle (nucleon) with a negative charge.

Proton: This is the subatomic particle with a positive charge.

Valency: The number of electrons on the outermost shell of an atom.

Atomic number: This is the number of protons in the nucleus of one atom of an element.

Mass Number: Total number of protons and neutrons.

Isotope: Atoms of the same element with the same atomic number but different mass numbers.

Isotopy: It is the existence of atoms of the same element with identical atomic numbers but different mass numbers due to the difference in the number of neutrons.

During the exams, students are expected to have a clear understanding of atomic structure and isotopy, as they will be tested on it. For more exciting quizzes, click here.
